Which equation can be used to solve the following word problem? Seth has 8 more nickels than dimes, and the total value of his coins is $2.35. How many nickels does he have? Let n represent the number of nickels.

Answer:

B) $6.00

Step-by-step explanation:

well divide 3.60 and you get 1.20

and the same for 4.80 divided by 4

so it be 1.20 times 5= he pays

To find out how much Cedric would pay for 5 songs, we divide the total cost by the number of songs and then multiply it by 5. Cedric would pay $6.00 for 5 songs.

To find out how much Cedric would pay for 5 songs, we first need to determine the cost per song. From the given information, we can see that the cost of 3 songs is $3.60 and the cost of 4 songs is $4.80. To find the cost per song, we can divide the total cost by the number of songs.

Since the cost per song is the same for both sets of songs, we can conclude that Cedric would pay $1.20 for each song. Therefore, for 5 songs, he would pay 5 x $1.20 = $6.00.

Answer:  Yes, there is something missing.

Step-by-step explanation:  Given that Charlie gathers apples pears and plums. The number of apples and plums are 10 partners, there are the same number of apples and pears.

Since there are 10 partners of apples and plums, so

number of apples = number of plums = 10.

Also, number of apples and number of pears are same, therefore, number of pears = 10.

Thus, total number of fruits = 10+10+10 = 30.

Hence, Charlie couls gather 30 fruits.

So, this was missing in the calculation.

Charlie can be made to gather more fruit by maximizing the number of

apples gathered which gives a total of 19 fruits.

Response:

The question is a word problem

Number partners of 10 are numbers that add up to 10

Therefore;

The number of apples + The number of plums = 10

The number of apples = The number pears

Required:

The number of pieces of fruit Charlie could gather

Solution:

Let x represent the number of apples, gathered, we have the following equations;

The number of plums = 10 - x

The number of pears = x

Which gives;

Total number of fruit = x + 10 - x + x = 10 + x

Where;

1 ≤ x ≤ 9

The maximum number of fruit Charlie can gather is therefore, when x = 9,  which gives;

Answer:

4 weeks

Step-by-step explanation:

Final answer:

After 5 weeks, you and your friend will have the same amount.

Explanation:

To find out after how many weeks you and your friend will have the same amount, we need to set up an equation and solve for the number of weeks. Let's assume the number of weeks is represented by 'w'.

Your balance in the bank after 'w' weeks can be represented by the expression: 48.50 + 9.50w. Your friend's balance after 'w' weeks can be represented by the expression: 1 + 2(9.50w). We want to find out when these two balances are equal, so we set up the equation: 48.50 + 9.50w = 1 + 19w.

Solving this equation, we get:

48.50 + 9.50w = 1 + 19w

48.50 - 1 = 19w - 9.50w

47.50 = 9.50w

w = 47.50/9.50

w = 5

After 5 weeks, you and your friend will have the same amount.

Answer:

Measure of one of the central angles in the regular pentagon is 72 degree.

Step-by-step explanation:

A Central angle states that the angle made at the center of the polygon by any two adjacent vertices of the polygon.

If you draw a line from any two adjacent vertices to the center, then they would make the central angle.

Since, it is given that the polygon we use here is regular pentagon.

⇒ All the central angles are equal.

The formula to find the central angle is:

Central Angle = [tex]\frac{360^{\circ}}{n}[/tex] where n is the number of sides.

Since, the measure of the central angle thus depends only on the number of sides.

Here, side(n) = 5 (Polygon is regular pentagon)

then;

Central angle = [tex]\frac{360^{\circ}}{5} =72^{\circ}[/tex]

Therefore, the measure of one of the central angle in the regular pentagon is, [tex]72^{\circ}[/tex]

Answer:

72 and 54 are your answers

Step-by-step explanation:

Answer:

The answer is 6.

Step-by-step explanation:

You need to have side x + 4 equal side 3x - 8. If you plug 6 into both equations, then you get x + 4 = 910and 3x - 8 = 10. The last side of the triangle equals 6. You then add all three sides together to get 25. 10 + 10 + 5 = 25.

This is an isosceles triangle (a triangle with 2 congruent/equal sides and 2 congruent angles)

If you look at the triangle, most likely side AB and BC are congruent.

Since the sides are suppose to be the same/equal to each other, you can do this:

AB = BC

x + 4 = 3x - 8       Subtract x on both sides

4 = 2x - 8    Add 8 on both sides

12 = 2x      Divide 2 on both sides

x = 6

You need to find AC.

AC = x, since you know x = 6, side AC is 6 units

Answer: A one-to-one correspondence between the parts of two figures is such that the corresponding parts are equal, then the figures are congruent.

The question pertains to geometric concepts of congruence, one-to-one correspondence, included side, included angle, and vector concepts in mathematics, such as orthogonal and parallel vectors, which are key concepts in solving geometry and trigonometry problems.

The question refers to several key concepts in geometry. When each member of a set, such as angles of a triangle, can be paired with one and only one member of another set, we have a one-to-one correspondence. This correspondence can be applied to situations such as pairing angles or sides of one geometric figure with another.

For example, let's consider two triangles. If each angle of the first triangle corresponds to an angle of the second triangle, and all pairs of corresponding elements (angles or sides) are equal, then those two triangles are congruent. This is the basic principle of congruence in geometry.

The angle formed by two sides of a triangle is called an included angle. The side of a triangle that is formed by the common side of two angles is an included side. In a right triangle, like in Figure 5.17, we see the terms adjacent side, opposite side, and hypotenuse, which are used for trigonometric calculations such as sine, cosine, and tangent.

The Pythagorean Theorem plays a crucial role for right-angled triangles, stating that the square on the hypotenuse is equal to the sum of squares on the other two sides. Also, the question talks about parallel and orthogonal vectors. Two vectors are said to be parallel if they have identical directions, while orthogonal vectors are perpendicular to each other, with directions differing by exactly 90°.

Final answer:

To find the total amount of juice in all the glasses, add the amounts poured by Maria and Collin. Maria pours 1 ¼ cups of juice and Collin pours 1 ½ cups of juice, so the total amount is 2 ¾ cups.

Explanation:

To find the total amount of juice in all the glasses, we need to add the amounts poured by Maria and Collin. Maria pours 5 glasses of juice, each measuring ¼ of a cup. So Maria pours a total of 5 x ¼ = 1 ¼ cups of juice. Collin pours 6 glasses, also with ¼ of a cup of juice each. So Collin pours a total of 6 x ¼ = 1 ½ cups of juice. To find the total amount of juice in all the glasses, we add 1 ¼ cups and 1 ½ cups, which gives us a total of 2 ¾ cups of juice.

Step-by-step explanation:

Since it's independent you use the formula:

P(A) x P(B) = P(A+B)

(4/5) x P(B) = (1/2)

Make common denominator

(8/10) x P(B) = (5/10)

P(B) = 5/8

If the events are independent, then the value of P(B) will be 5/8.

The chances of an event occurring are defined by probability. Probability has several uses in games, and in business to create probability-based forecasts.

For independent events;

P(A) x P(B) = P(A+B)

(4/5) x P(B) = (1/2)

P(B) =(1/2)×(5/4)

Answer:

[tex](y-135)=45(x-3)[/tex]  

Step-by-step explanation:  

Let x represents the number of hours and y represents the number of miles.

We are told that Luz drives at an average speed of 45 miles per hour. She has driven for 3 hours and has traveled a distance of 135 miles.  

We can see from our given information that slope of line is 45 as with each increase in number of hours (x), change in distance (y) is 45.

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{135-0}{3-0}[/tex]

[tex]m=\frac{135}{3}[/tex]

[tex]m=45[/tex]

Since the equation of line in point-slope form is : [tex](y-y_1)=m(x-x_1)[/tex], where m represents slope of line and [tex](y_1,x_1)[/tex] represents a point the line passes through.

Upon substituting our given values in point-slope form of equation we will get,

[tex](y-135)=45(x-3)[/tex]  

Therefore, the equation represented in point-slope form will be: [tex](y-135)=45(x-3)[/tex].

Answer:

The slope of the linear equation is  45.

A point on the graph of a linear equation will be (3, 135).
